A number of writers create poetry suitable for mother-daughter greeting cards, from well-known poets such as Faye Diane Kilday, Michael Burch and Raymond A. Foss to unknown poets who contribute to online anthologies. The eighth-century Japanese poet Otomo no Sakanoue Iratsume wrote about a mother's love for her daughter.
When searching for poetry for greeting cards, it's often a good idea to extract a few lines from a longer poem, such as "Mother's Smile" by Michael Burch. Quotes must acknowledge the author of the poem and may not be used for commercially sold greeting cards, as this may infringe copyright laws. Instead, use poems in the public domain.
